Abstract
A single magnetic head assembly having vertically stacked separate units of recording and playback cores is comprised of a first unit of at least one recording cores, and a second unit of at least one playback core which is located in stacked positional relationship relative to the first unit. These units of cores are arranged to be jointly shifted vertically to meet the required track of the magnetic tape when used, to thereby utilize that particular unit of cores optimum for recording or playback, as desired.
